<font color="0077aa"><font size="+1">Yasmine</font></font>, hey sorry, I haven't had time to follow up here for awhile.. again, hope this is not too late.
For my practise, I use time frame and the grade of the fever to decide if there's a need to go see doc.
Time frame will be 3 days, meaning if my child has been having low grade fever(Below 38.5 degrees C) for more than 3 days while not having any other symptoms then I'll visit the doc.
1 of the following situations, then I'll proceed to see doc:
1. If my child has been having high grade fever(above 38.5degrees C) for more than 24 hours after being fed appropriate medicine*.
2. If my child has high grade fever and other serious symptoms such as a bad fall, vomiting, sight of blood.
3. If my child has low grade fever but with unmanageable rashes all over.
4. If my child has low grade fever but with swells in her facial features.
5. If my child has low grade fever but whines/cries for more than 3 hours in a row.
(These are what I can think of now, there maybe more..)
*Appropriate Medicine I keep at home for fever are:
Paracetamol - for low grade fever
Bifen Suspension - for high grade fever, I don't use suppository becos Bifen is good enough.
I suggest all mummies to have these type of meds standby at home and it'll be quite a battle to tame it down once it hits 40 degrees C.
Going to A&E in the middle of the night is only going to be taxing on both the kid and the parents. So I rather tame the fever first then when it's of normal clinic hours, then I'll bring bb to see doc.
Hope this helps and that Ethan is all well now
and in future if u need faster paced help, u can PM me ya..
his weight has not dropped tho, so i guess its just that he's growing taller n 'stretching' out? think thats common for toddlers rite?
